Investigation of ductility in hybrid and high strength steel beams

International Journal of Steel Structures, 2014
Compactness and lateral support configuration provisions for design of steel beams are formulated so as to ensure that the resulting beam exhibits adequate ductility. It appears from the current research that slenderness limitations are not valid for beams made of the high strength steel grades. In this paper an attempt is made to study on influence of

The rotational capacity of beams made of high-strength steel

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2017
Within the scope of the research project RUOSTE, the material characteristics and rotational capacity of beams made of high-strength steel grades S700 and S960 were investigated. In two test series, the achievements of cross-section class 1 and 2 were investigated.

Flexural-torsional buckling of high-strength steel beams

Journal of Constructional Steel Research, 2016
Abstract High-strength steel (HSS) is gaining widespread acceptance in contemporary engineering structures, with grades of up to 690 MPa being included in many design standards. However, although strength grades well in excess of 690 MPa are possible with modern metallurgical processes, these are not compliant with most design codes of practice.

Influence of beam oscillation on laser beam welding of high strength steels

2022
Hochfeste Stähle sind aufgrund ihres guten Preis-Leistungs-Verhältnisses vor allem für hohe Produktionsstückzahlen ein essentieller Baustein zur Umsetzung des werkstofflichen Leichtbaus. Um den höheren Anforderungen an deren schweißtechnische Verarbeitung gerecht zu werden und Nahtdefekte zu vermeiden, gilt es den Schweißprozess entsprechend anzupassen.

Use of High-strength Steel for Simply Supported Beams

Engineering Journal, 1986
As stated by AISC, high-strength steels have proven to be economical choices where lighter members, resulting from use of higher allowable stresses, are not penalized because of instability, local buckling, deflection or other similar reasons. The reduction of dead load and associated savings in shipping costs can be significant factors.

Behaviour of normal and high-strength castellated steel beams

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2012
This paper investigates the design and behaviour of normal- and high-strength castellated steel beams under distortional buckling. An efficient non-linear three-dimensional finite-element model has been developed for the analysis of the beams. The initial geometric imperfection, residual stresses and material non-linearities of flange and web portions

Flexural Strength and Stiffness of High Strength Concrete Beams with Exposed Main Steel

Advanced Materials Research, 2012
In a number of previous publications, results were reported for a series of extensive and carefully conducted tests on large scale reinforced concrete (R.C.) beams with various extents of loss of concrete cover and exposure of main reinforcement along their spans, with such areas of simulated damage being located within their regions which are ...

Flexural Strength Design of Concrete Beams Reinforced with High-Strength Steel Bars

ACI Structural Journal, 2008
Current design requirements limit the allowable design strength of high-strength steel reinforcements to 80 ksi (550 MPa), which limits engineers from fully using the enhanced strength characteristics of low-carbon and chromium high-strength steel. In this paper, a methodology is presented for the flexural strength design of concrete beams reinforced ...

Strength and ductility of high strength concrete-filled steel tubular beam–columns

Journal of Constructional Steel Research, 2009
The ultimate strength and ductility of high strength thin-walled concrete-filled steel tubular (CFST) beam–columns with local buckling effects, are investigated in this paper, using a performance-based analysis (PBA) technique. The PBA technique accounts for the effects of geometric imperfections, residual stresses, strain hardening, local buckling and
